B 317,811317,811
C 9,227,4659,227,465
D 604,419
Solution
To find the 35th term of the Fibonacci sequence using Binet's Formula, we use the following equation:
Where:
- is the nth Fibonacci number,
- is the position in the sequence (in this case, ).
Let’s calculate the 35th term using this formula. I'll simplify the terms and compute the result.
Approximate calculation:
Now, using these values and computing:
Let me compute the value.The 35th term of the Fibonacci sequence is approximately .
Thus, the correct response is C.
